Answer:
x-y=5
Step-by-step explanation:
If a line has a slope of 1, its function can be write as x-y=c
insert point (7,2),t then we can find out the constant c=5, so the equation of this line is x-y=5
All angles are of triangle and thus give sum of 180⁰
x + 5 + 7x - 5 + x = 180⁰
9x = 180⁰
x = 20⁰

Answer:
The solutions are (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
Step-by-step explanation:
The equations are:

and

We make y the subject in the second equation to get;

We substitute into the first equation to get:


and 
The solutions are (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
